Turbotax Premier asked for data from Blocks 2 & 3 from my 1099-R from OPM. There are no Blocks 2 or 3 in OPM 1099-Rs going back as far as 2008.

1099-Rs from 2008 thru 2018 start with Block 1, then Block 2a, and then skip to Block 5.  During all those years, Turbotax never asked for data from Blocks 2 & 3, but did in 2018.
